A novet toughened epoxy resin was obtained by using a precopotymer of epoxy resin and hydroxy-terminated butadiene-acrylonitrile copolymer(HTBN) and amine curing agent.The cured toughened resin has excellent mechanical properties due to the two-phase structure, which has been observed from SEM and TEM.
